PRIMARY nnnerare BATTERY.

I To all whom it may conrer'nv.

-l 3e it known that I, Gnonen LU'rz; citizen of the United States, and resident of Plainiield, in the county of Union and State of New Jersey, have inventedcertain new and useful Improvements in Primary Electric Batteries, of which the following is a specification. M- invent-ion relatls to improvements in primary electric batteries of the class in.

oXid, such as cupric oXid, and 'a positive electrode comprising zine.

The object of my invention is to provide improved meansforsupporting the electrodes from the cover of the ar in proper correlation, to thoroughly insulate the various parts, and to provide sim le and convenient means for permitting repl ,ds required.

In carrying out my invention I provide an insulator that is supported by the cover of the jar and from which .the frame of the oXid plate is suspended a supporting rod passing and t e zines.

M invention also comprises the novel details'of improvement and combinations of arts that will be more fully hereinafter set lbrth and then-pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

. Figure 1' is a-perspective "view illustrating my improvements in position; Fig. 2 is a section on the line 2, 2, in Fig. 1, showing the jar and cover; Fig. 3 is a detail sectional 'view, and Fig. 4 is a section on'the line 4, 4, in Fig. 3.. a

Similar numerals of reference indicate-corresponding parts in the several views.

Any suitable jar or rec'e taclel is prorefera ly of insulating material; andfrom t e cover the electrodes are hung.

7 At 3 is a frame which maybe of channel metal, and which supports the plate 4 of depolarizing material, such as 'a t gompressed plate comprising cupric oxld. Frame 3 s shown provided with cross bars 3, 3", re-

spectively above and below plate 4, the cross bars 3*, 3 being shown provided with lugs 3 passing througl'i holes in frame 3, and bent down to secure the cross bars in the frame and assist in holding plate 4. The upper art of frame 3 is n'ovided with a suitable hole through which a metal rod 5 passes,

through the insulator suspending the latter I Specification of Letters Patent.

which rod also passes through cover 2 and is detachably supported thereon as by nut 6 on the threaded end of' the rod.

At 7 is an insulating block having an opening" through which rod 5 passes, which block is shown provided with a. recess 7 at its upper end receiving frame 3, and said 1 mine is thus supported and is in circuit with red 5, as by contact therewith. The positive electrode or zinc plate 8 is suspended by rod 5 and shown provided at its upper end with an inwardly bent portion or lug 8* having a hole receiving a reduced end or hub 7 b on insulating block 7', an insulating washer 9 being interposed between the inwardly bent portion or lug '8 of zinc 8 and" the head or projection 5. of-ro'd 5. I have shown two positive electrodes or Zines 8 each provided with an a-pertured lug 8 receiving hub 7 said zines being located on opposite sides of zines are in contact with each other, are properly supported and held in position, and are insulated from frame 3 and plate .4. Zinc 8 is connected with a suitable binding post 10 on cover 2,

I as by a wire 11,

By means of my improvements the elements of the batterymay be readilyreplaced, as. it is merely necessary to remove rod 5 from the cover to permit detachment and replacement of the negative and positive electrodes as required. The electrodes all being sus ended from the cover by rod 5, the zines ein supported independently of frame 3 and the positive and negative elements thoroughly insulated from each other, affords an efficient construction, Without danger of short-eireuiting of the elements, and a cheap and convenient battery may be produced.

Having now described my invention'what Iclaimisz- 4 1. A primary electric battery comprising a cover, a supporting. rod depending from the cover, an insulating block supported by the rod below the cover, a frame supported by the block and carrying a depolarizing late, and a positive electrodesupported by and insulated from the said rod.

2. A primary electric battery comprising a supporting rod, an insulating block thereon, aframe supported by the block and carrying a depolarizing plate, and a positive electrode provided with an opening receiving a. por' tion of said insulating block andsupportedfi by said rod.

3. A primary electric battery provided with a cover, a rod depending from the cover, an insulating block upon the rod provided with a recess, a frame supported in said recess and in circuit with said rod, said frame carrying a depolarizing plate, and a positive electrode supported by said rod! and insulated therefrornby said block.

4. A primary electric battery provided with a cover, a rod depending from the cover, an insulating block upon the roe provided with a recess, a frame supported in said recess and in circuit with said rod, said frame carrying a depolarizing plate, a positive electrode supported by said rod and insulated therefrom by said block, said block having a hub projecting through an opening in the positive electrode, and an insulating piece between said electrode and an extension on said rod.

5. In a primary electric battery, :1 rod having a head at one end, an insulating block provided with an opening mounted upon said rod, a frame carried at the upper cud of said block and in circuit with said rod, a positive electrode supported by the rod at the lower end of said block and insulated by the block from the rod, and means for insulating the positive electrode from said head.
